GRAIN-CAR DOOR.

SPECIFICATION forming part of Letters Patent No. 237,305, dated February1, 1881.

` Application filed December 1], 1880. (No model.)

To all whom it may concern:

Be it known that I, NOAH MOSER, of Loogootee, in the county of Martinand State of Indiana, have invented certain new and useful Improvementsin Grain-(lar Doors; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form part of this specification, in which- Figure 1 is a sideview, Fig. 2 a central vertical section, and Figs. 3, 4, and 5 are'detail views, of my invention. p

The nature of my invention relates to doors for grain-cars; and itconsists in such details of construction as will be hereinafter morefully described, and specifically pointed out in the claims.

In order to enable others skilled in the art to which myinventionappertains to make and use the saine, I will now proceed to describe itsconstruction and operation.

A represents the door-frame, and B the roofframe, of a grain-car. Thedoor-frame is provided with the usual auxiliary door C, which is packedaround its edges with rubber, felt, or any suitable material to form atight joint.

On the face of the door, at each side, parallel with the door-frame, isarranged a rackbar, E, and pivoted to the adjacent frame are two bars, DD, whose lower ends are formed with a hook, d, and point d', as shown inthe drawings. The .pivot o of these lever-bars passes through a slot, c,extending lengthwise of the bars, which are thus adapted to be drawnback so their lower ends will clear the door whenbeing turned down, andthen pushed forward to engage the point d with the notched bar E andforce the door upward, as will presently be explained.

To the bars E, or to the door near the frame, l secure a tension-loop,constructed preferably as follows: To the door I secure a screw, j',which passes through one end of a link, f', as seen in Fig. 5. This linkmay be screwed on or off the screw f, to increase or diminish thepressure by which the `door is held in place, as will be readilyunderstood. rIhe link j" is engaged with the hook d onthe lower end ofthe lever-bar, and the outer end of kthe bar being lifted the door isdrawn downward The inside of the door-frame A is provided 6o withvertical guide-rods b b, extending to the root of the car, and the topof the auxiliary door C is furnished with short projecting arms h h,having holes for the passage of the guiderods b b. The door thus guidedmay be shoved upward until the `projecting arms reach the upper ends ofthe guide-rods, when the bottom of the door may be swung inward andupward till it reaches the roof of the car, where Ait may be secured bya button or other fasten- 7o ing till needed.

When the door is in use it is secured by means of the tension-links andlever-bars, as alreadyr described.

When the car is full of grain the pressure on the door is so great thatit is often difficult to raise it, and in that case, after the upperends of the levers have been released, they are turned down and pushedinward till their points d engage with the notched bars E, 8o when thedoor may be prized upward as far as necessary, as will be seen byreference to the drawings. 5

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination, with a sliding door, of a pivoted sliding leveradapted to elevate and lock the door, substantially as herein set forth.

2. The combination,withasliding door pro- 9o vided with a rack-barattached thereto, of a pivoted sliding lever, constructed at its lowerend to engage with the rack-bar and raise the door, substantially asherein set forth.

3. The combination, with a sliding door, of 9 5 a rack-bar attachedthereto, an adj Listing-link, and a pivoted lever adapted at its lowerend to both engage with the rack-bar to raise' the door and with thelink to lock the door, substantially as described.

4. The slotted and pivoted lever D, formed with hook ol and point d', incombination with IOO screw f, link f', and rack-bar E, all construct- Intestimony that I claim the foregoing as ed and arranged. to operatesubstantially as my own I affix my signature in presence oi and for thepurpose set forth. two witnesses.

5. The combination,in a grain-car, of a door, 5 G, adapted to be raisedand swung` inward NOAH MOSER.
